Placental protein 14 and progestagen-dependent endometrial protein are immunologically indistinguishable

Hum Reprod. 1986 Jan;1(1):7-8. doi: 10.1093/oxfordjournals.humrep.a136349.


Placental protein 14 isolated from the human placenta and its adjacent membranes, and progestagen-dependent endometrial protein (PEP) isolated from the endometrium have been described independently by two groups. We report results of the radioimmunological and immunodiffusion tests which show that the proteins are immunologically indistinguishable from each other.
